This morning it was really cold in New York around 9 degrees .My car started to make a strange noise from the engine.I thought it was just the cold causing this but the "battery charge warning " came on . I call my local MB service tech and was asked if I saw the neg and pos symbols when I answered yes he seemed to get excited and started telling me about the alternator might be bad. On the way home with car the warning kept flashing battery charge, then the abs brakes warning came on, then the srs warning, and the asr warning came on and then the fss display went totally blank. Then the car must have went into the limp mode because the transmission felt like it was slipping but it got me home. Has anyone of you ever had an alternator go bad on you and is it covered under the starmark warranty?
